云南省废弃矿山改造为抽水蓄能电站发展前景研究

Research on the Prospect of Transforming Abandoned Mines into Pumped Storage Power Stations in Yunnan Province

根据云南废弃矿山采空区空间大、水资源充足的结构特点,可以将废弃矿山改造为抽水蓄能电站,以提高能源利用效率。本文介绍了现有矿山改造抽水蓄能电站发展模式,包括全地表露天矿坑模式、半地表塌陷矿井模式和全地下废弃矿井利用模式;根据某废弃矿山及周围有地势高度差的山体设计上、下水库,计算得到建设装机容量为1MW的抽水蓄能电站时,上下水库蓄能库容为170182.39m^(3),发电机一次性最大发电量为56350kW·h,水泵最大耗电量为89347.45kW·h。

The abandoned mine in Yunnan has the characteristics of a large space and sufficient water resources,and the pumped storage power station can be built in the existing structure.This paper introduces the development mode of the existing mine reconstruction pumped storage power station,including the full surface mode of the open pit,the half surface mode of collapsed mine,and the full underground utilization mode of an abandoned mine.In addition,it is calculated that the installed capacity of the pumped storage power station is 1 MW,the energy storage capacity of upper and lower reservoirs is 17,0182.39 m^(3),the maximum generating capacity of generators is 56,350 kW·h,and the maximum power consumption of water pumps is 89347.45 kW·h.
